Description

YU

The invention relates to telemechanics and can be used to control technical teaching aids (slide projectors, cinema sets, graphical projectors, television sets, tape recorders, electrified layouts and installations), household electrical appliances, etc. The devices for remote control of various electrical devices are known, containing a fixed control transmitter, a receiver and a deflector, the outputs of which are connected to the inputs, execute 1 device f. A disadvantage of the known devices is their limited functional capabilities and a small number of controlled objects. The closest in technical essence to the proposed is a device for remote control, comprising a transmitter connected to the receiver, a receiver output connected to the input of the decoder, a selection unit whose input is connected to the first output of the decoder, and actuators 2 j. A disadvantage of this device is the low information content, due to the small number of stages for the selection of signals in terms of their temporal separation. The purpose of the invention is to increase the information content of the device. The goal is achieved: the fact that a remote control device containing a transmitter connected to a receiver, an output, a receiver is connected to the input of the decoder, a selection unit whose input is connected to the first output of the decoder, And actuators, a time relay, a switch, the display unit and triggers, the time relay inputs are connected to the first outputs of the decoder and the selection unit, the second outputs of the decoder are connected to the first inputs of the switch, the second input of which is connected to the output of the time relay and the first input of the display unit, the second outputs of the selection unit are connected to the second inputs of the display units, the third outputs of the selection unit are connected via triggers to the third inputs of the switch, the outputs of which are connected to the actuators. FIG. 1. a functional diagram of the proposed remote control device is presented; in fig. 2 is a diagram of its switch and decoder. The device contains a transmitter (cogland control) 1, a receiver 2 and a decoder 3 (commands), switch 4, time relay 5, triggers 6 and 7, a selection unit (duration) 8, the first 9, the second 10, the third 11 and the fourth 12 groups of actuators, display unit 13. In FIG. 2 shows pins 3, - 3 of the decoder 3 and the relay 14, 15 and 16 of the switch 4. The device operates as follows. When a service command is sent with a duration (t: signal from the first output of the decoder 3 ..., the control input of time relay 5 and the selection unit (signals for duration) 8 is received. Time relay 5 generates a control signal with duration T sufficient to transmit one work command. According to this signal, switch 4 switches the outputs of the decryptor. Torus 3 from the first group of actuators 9 to the fourth group of actuators 12 at time T. During this time, you can send a command to one of the actuators In order to send a command to another of the executive elements of the same group, the service command must be sent again, and then the corresponding work command. If the duration of the command command (SC) t is iib, after the time the service command has expired, switch 4 is connected again The first group of actuators 9 goes to the decoder 3. At IC duration more than ti from the third output of block 8, the second input of time relay 5 receives a signal that blocks the output of the signal from time relay 5. If the duration of the IC is tJo. 7f then from the first output of block 8 a signal arrives at the counting input of the trigger. that notion. The output voltage of trigger B goes to the second input of the switch 4. At the same time, a second group 10 of executive elements is connected to the decoder of the first one. With the duration of the IC. The command, from the second output of the block 8, enters the control input of the trigger 7, converting it to a single state. According to the signal from the output of the trigger 7, the switch 4 connects to the output of the decoder 3 a third group of actuators 11, instead of groups 9 and 10. The reverse switching of groups is performed by retransmitting the corresponding service command. Thus, the number of executable commands is 4 (11-1), while

the known device allows the re-- to give only N commands.

Consider the work of individual nodes of the device.

In the initial state, the outputs of the decoder 3 (in Fig. 2) are normally open contacts of the output relays of the decoder 3 — HL; through the contact groups 14, 15 and 16 of the relay, switch 4 is connected to the first group of outputs. Through the normally closed contacts of the same relay, the voltage is applied to the low-frequency lamp of the display unit 13. When issuing the command of the SC closure: g

The pins of the decoder 3 are connected and the signal is fed to the input of the selection unit 8, which separates the signals according to their duration and torque. effects of these signals.

5 Such a selection allows for the separation of signals of the same duration, belonging to different groups, due to which the information content of the device increases, since

10 the same communication channel as in the known device, it is possible to control several groups of objects.
